Rausan Ali Mondal, a mason by profession, slipped and fell into the well at Eksara village.
Disaster Management Minister Javed Khan said in Kolkata that fire brigade and disaster management personnel were carrying out rescue work at the site.
"Water is being pumped out from the well where some gas was also found. Divers along with masks, search lights and generator have been sent to the spot," Khan said.
The incident came hours after the body of four-year-old Mahi was pulled out from a 70-feet-deep borewell near Manesar where she was trapped for the past four days.
